雨中动漫学生肖像

Create a polished anime-style vertical portrait of a melancholic high school student sitting beside a classroom window on a rainy day. The character is {argument name="character gender" default="androgynous male-presenting"}, shown from the chest up in a close three-quarter side view facing left, with their head resting on one hand in a tired, contemplative pose. They have {argument name="hair color" default="dark navy-black hair with subtle purple highlights"}, messy layered bangs, loose wisps around the neck, and the back hair tied into a small tousled bun; one visible ear has a small round silver stud earring. The face should be intentionally covered by a large flat opaque rectangle centered over the facial area, colored muted gray-lavender with a soft vertical gradient, hiding the eyes, nose, and most expression. Dress the character in a refined dark navy school blazer with white piping, brass buttons on the cuff, a crisp white shirt, and a loose {argument name="tie color" default="purple"} necktie. Set the scene inside a quiet classroom with a wooden windowsill, pale curtains, and tall window frames; outside the glass, show rain droplets, a hazy gray-blue city skyline, distant buildings, and blurred trees. Use cool rainy lighting from the window, soft reflections, delicate linework, detailed hair strands, cinematic shading, and a subdued blue-purple color palette. Composition should be vertical 2:3, intimate and slightly cropped at the top of the hair bun and lower torso, with the character occupying most of the frame and the rainy window background visible on the left and right. No text, no watermark, no extra characters.
